Java:change modifier getRadius()to static

interface NewShape
{
 void draw();	
}
interface Circle extends NewShape
{
  void getRadius();
  int  radius=10;
}
class NewCircle implements Circle 
{
  public void getRadius()
  {
	  System.out.println(radius);
	 
  }
  public void draw()
  {
	  System.out.println("cool");
  }
}
class ExtendInterface extends NewCircle
{
 public static void main(String[]args)
 { 
	 Circle nc=new NewCircle();
	 Circle nc1=new NewCircle();
	 nc.getRadius();
	 nc1.draw();
 }
}
